Factorio Mods vs OpenRA Resource Center

Factorio Mods is the Mod Portal and in-game system for finding and managing mods for Factorio. The portal lets users search by title, internal name, summary, or username, then narrow results by categories and tags. Authors can upload mods, while users can access previous versions and discussion threads. In Factorio, the Mods menu handles downloading, installing, checking for updates, and enabling or disabling mods; it also obtains required dependencies.

When joining a modded multiplayer game, Factorio can download and enable the server's mods at their exact versions. Mods can change gameplay, for example by adding machines or informative GUIs. They are written in a modified version of Lua 5.2 and follow a required structure. The Mod Portal API supports browsing and downloading available mods, with basic endpoints that do not require authentication. Factorio runs on Windows, macOS, and Linux, and mods are distributed through the in-game manager. The listed plan is free. Uploading requires a licensed Factorio copy and a Factorio.com account; portal functionality requires a verified purchase.

OpenRA Resource Center is a free website for sharing maps and other game-related files within the OpenRA community. It supports standard, advanced, and modded maps, as well as missions, for three games. Players can upload a map and select it in a game they host or join; other players joining can automatically download it. Browsing filters cover mod, category, format, parser, tileset, player count, author, and uploader, with search by title, description, or hash. Listings show details including author, uploader, revision, player count, comments, and rating. Users can view revisions and maps with reports, or filter for duplicates, advanced maps, Lua maps, and outdated maps. The Map API supports map downloads and information retrieval by hash or ID, including details for the newest map. Map information is returned as JSON, with YAML available by adding a `/yaml/` URL prefix. The site documents map storage locations for Windows, Mac OS X, and Linux. Sign-in supports local accounts and social login. Upload rules limit submissions to OpenRA-related files and require written permission for another person's work.
